Shadow and Sound Protection: Prepared to Meet Any Demand
The acoustical and optical effects of a wind power plant must be taken into account from the initial planning stage. The Federal Immission Control Act (Bundes-Immissionsschutzgesetz) prescribes protective measures against noise or air pollution. As a consequence wind turbines that are situated close to residential areas must not exceed certain sound emission values or shadow periods. REpower wind power plants ensure you are perfectly equipped to meet these demands.
Innovative Control of Sound and Shadow
The sound management of REpower wind power plants provides sound protection by turning down the number of revolutions to a lower sound level. In this way legal requirements can be met without any problems. As all of our wind power plants are gearbox-driven, sound protection by speed ad-justment can be realized at reasonable costs.
Optical factors must also be considered, e.g. the shadow cast by the rotor on adjacent properties. Should this shadow period exceed certain legal reference values (in Germany i.e. 30 hours p.a./30 minutes p.d.) it must be shortened. Our shadow management takes care of this: Via a light sensor and an integrated timer, the shadow cast module recognizes sunlight level and time. If reference values are exceeded, the wind power plant is stopped for the necessary period of time – avoiding any possible disturbance of the local residents.
